If your Dell PC was blocked from getting KB5101650 due to these conflicts, KB5121767 will both apply the missed updates and resolve those specific issues.([support.microsoft.com](https://support.microsoft.com/en-US/servicing/os/windows-11/2026/07/july-14-2026-kb5101650-os-builds-26200-8875-and-26100-8875?utm_source=openai))\n\n### For devices *not* affected (e.g. non-Dell, no IPF driver conflict):\n- The update is **optional**. Microsoft says it's \u201conly recommended for devices affected by this issue.\u201d([support.microsoft.com](https://support.microsoft.com/ja-jp/servicing/os/windows-11/2026/07/kb5121767-out-of-band?utm_source=openai))  \n- It may appear in Windows Update if you have \u201cGet the latest updates as soon as they\u2019re available\u201d turned on.([support.microsoft.com](https://support.microsoft.com/ja-jp/servicing/os/windows-11/2026/07/kb5121767-out-of-band?utm_source=openai))  \n- If you have no issues and that toggle is disabled, you can safely skip it. If you install it anyway, there are no known reports (as of now) of it causing major problems on unaffected systems.([allthings.how](https://allthings.how/kb5121767-microsoft-s-emergency-fix-for-dell-pcs-broken-by-the-windows-11-update/?utm_source=openai))\n\n---\n\n## How to tell which category you fall into\n\n1. **Check your device model/manufacturer**: Is it a Dell, especially with Intel IPF driver installed?  \n2. **Check for symptoms**, such as:\n   - Unexpected shutdowns  \n   - Overheating  \n   - Poor battery life  \n   - Performance issues  \n\n3. **Check your build number**:\n   - After installing, Windows 11 should show **build 26200.8894** (if you're on 25H2) or **26100.8894** (if you\u2019re on 24H2).([allthings.how](https://allthings.how/kb5121767-microsoft-s-emergency-fix-for-dell-pcs-broken-by-the-windows-11-update/?utm_source=openai))  \n4. **Update settings**:\n   - If you\u2019ve enabled \u201cGet the latest updates as soon as they\u2019re available,\u201d you may receive this update even if you're not affected.([support.microsoft.com](https://support.microsoft.com/ja-jp/servicing/os/windows-11/2026/07/kb5121767-out-of-band?utm_source=openai))\n\n---\n\n## My recommendation\n\n- If you're using a **Dell device** and have experienced any of the issues \u2014 yes, install KB5121767 as soon as you can.\n- If you're using a **non-Dell device** and everything\u2019s working fine, you can skip it and wait for the regular Patch Tuesday update.\n- If unsure, check whether your current version has the symptoms or if your update settings might trigger this automatically.\n\n---\n\nIf you want, I can help you check whether your specific PC is affected (based on model, driver versions, etc.), to decide whether you should or shouldn't install this update. Do you want to go through that?"
